How this works

This calculates your exact age by counting the precise number of years, months and days between your date of birth and any reference date โ€” by default, today. It also tells you the total number of days you've been alive and how many days remain until your next birthday, calculated by comparing your birth month/day against the reference date and rolling over to the next year if your birthday has already passed this year.

Frequently Asked Questions

Why does my age in months/days look different from a simple year subtraction?

A simple subtraction (e.g. 2026 โˆ’ 1995 = 31) ignores whether your birthday has occurred yet this year. This calculator accounts for the exact month and day, so if your birthday hasn't happened yet this year, it correctly shows one year less plus the precise remaining months and days.

Can I calculate age as of a future or past date, not just today?

Yes โ€” this tool lets you set the 'Calculate Age As Of' field to any date, which is useful for eligibility checks (e.g. age on a specific exam date or joining date) rather than just your current age.

Does this account for leap years?

Yes, the calculation is date-based (not a fixed 365-day approximation), so leap years are automatically handled correctly in both the day count and the years/months/days breakdown.
